Destination unit number selectionOn unit firmware Ver. 1.8 or later, adding a specification of HEE (238) for the destination unitnumber allows for communication to be carried out regardless of destination unit number.■ Specifying the storage area of a destination unit by using [D] and [n]Specify "0" for [D] as the device number.Specify the memory area of a destination unit that stores sent data, by combining [D] (type) and[n] (address).Example 1: [D]: DT0, [n]: K100↓DT100Example 2: [D]: DT0, [n]: HFFF0↓DT65520■ Specifying a COM port number for the F469 (UNITSEL) instruction (only for thetype with Ethernet Function)Specifying HE in the upper four bits of [S1+1] of F145 (SEND) enables operand [S2] for theF469 (UNITSEL) instruction. The following figure shows that the F469 (UNITSEL) instructionspecifies S1=K0 (serial communication port) and S2=K1 (COM1).[S2] of F469 (UNITSEL) K0 K1 K2Port number COM0 COM1 COM2■ Flag operationsName DescriptionR9007R9008(ER)Turns ON when the [S1] / [S1+1] control data value is outside the specified range.Turns ON when the [S2] or [D] area is exceeded, if the number of words specified in [S1] istaken during transfer in word units.Turns ON when [D]+[n] exceeds the [D] areaTurns ON when the operation mode of the target COM port is other than computer link.Word unit● If [D] is DT / LD, turns ON when [n] is not from 0 to 99999● If [D] is WY / WR / WL / SV / EV, turns ON when [n] is not from 0 to 9999.Bit unit● Turns ON when [D] is not WY / WR / WL● Turns ON when [n] is not from 0 to 999.8.1 Communication InstructionWUME-FP0HCOM-06 8-5
